- W3133561812 abstract "• AgCl-doping and Sb-alloying enhance thermoelectric performance of SnTe stepwise. • AgCl-doping simultaneously enlarges band gap and achieves band convergence of SnTe. • Dense point defects effectively reduce lattice thermal conductivity of SnTe. • Sb-alloying effectively optimizes carrier concentration of SnTe. As an eco-friendly thermoelectric material, SnTe has attracted extensive attention. In this study, we use a stepwise strategy to enhance the thermoelectric performance of SnTe. Firstly, AgCl is doped into SnTe to realize band convergence and enlarge the band gap of AgCl-doped SnTe. AgCl-doping also induces dense point defects, strengthens the phonon scattering, and reduces the lattice thermal conductivity. Secondly, Sb is alloyed into AgCl-doped SnTe to further optimize the carrier concentration and simultaneously reduce the lattice thermal conductivity, leading to improved thermoelectric dimensionless figure of merit, ZT . Finally, (Sn 0.81 Sb 0.19 Te) 0.93 (AgCl) 0.07 has approached the ZT value as high as ∼0.87 at 773 K, which is 272 % higher than that of pristine SnTe. This study indicates that stepwise AgCl-doping and Sb-alloying can significantly improve thermoelectric performance of SnTe due to synergistic band engineering, carrier concentration optimization and defect engineering." @default.
